Abstract
Abstract One multiphysics model, integrated corrosion inhibition (ICI) model, has been theoretically introduced and experimentally validated for the integrated evaluation of water-oil partitioning, aggregation, adsorption/desorption, and corrosion inhibition of mixed surfactant inhibitors in salt-containing water-oil-steel pipe (WOS) environments. The {ICI} model is based on three major sub-models which consider water-oil surfactant partitioning, micellization, effective adsorption/desorption on substrate, surfactant type, surfactant-solvent interactions, surfactant-counterion pair, and lateral surfactant interactions etc., and intended to serve as a basic framework in the design, selection, optimization, and utilization of various pure and mixed surfactant inhibitors in {WOS} environments.
Microsoft is Ending Support for Windows 7
Microsoft will discontinue support for Windows 7 on January 14, 2020 which means Gamry will also be discontinuing support for Windows 7. If you are upgrading to Windows 10, like many companies and institutions, you need to be running Version 7 of our s oftware . Please note that only USB and Ethernet-based instruments can run in Version 7. Eligible users can download the latest version of our software through our online Client Portal .
If you haven't already registered your instrument, you can do so through the Client Portal .
Please email Technical Support if you have any questions regarding this transition. Please be sure to include your instrument model and serial number when contacting us.
